The 633 resembles Ketos wave wings in many parameters. There is a little griping about this if you dig through the French foil forum.
Have not heard of any formal accusations of stealing though, whoever the designer might be.
Design elements of wing shapes, like boat hull shapes or surfboard shapes, are not patentable anyway, as far as I know.

Not even close. The wings have different profiles, outlines and curves.
